LUBRICATING JOURNAL-BOX.

Specification of Letters Patent.

Patented J une 16, 1914.

' To'aZZ whom it may concern Be it known that I, ELIEL L. SHARPINEGK, acitizen of the United States, residing at lVinthrop, in the county ofSuHolk and State of Massachusetts, have invented certain new and usefulImprovements in Lubricating Journal-Boxes, of which the following is aspecification, reference being had to the accompanying drawings, formingpart thereof.

rIfhis invention has reference to improvements in lubricating journalboxes having roller bearings.

The object of the invention is to improve the construction oflubricating journal boxes'having roller bearings adapted to ro tate insaid boxes whereby the shaft or axle journaled in the rollerbearing andsaid bearing are held from any considerable longitudinal movement insaid journal box and whereby, when necessary, the roller bearing as awhole may be removed from the journal box.

rIhe invention consists in the improved journal lbox and its closure ashereinafter more fully described and pointed out in the claim.

Figure 1, represents a longitudinal vertical sectional view of theimproved journal box as taken pn line 1-1 Fig. 2. Fig. 2, represents anend view of the same with the cap removed, except for a small fragment,parts of the box being broken away.

Similar characters of reference designate corresponding partsthroughout.

As shown in the drawing the journal box comprises the outer shell orcasing 5 having at its inner end the wall 6 and at its outer end thestepped shoulder 7. The concentric bore of the casing 5 is completed, atthe lower portion by the ways 8, 8 integral with said wall 5 and withthe depending integral wall 9 having the ends 10 and 11 which 1s adaptedto contain oil orv forms an oil chamber through which said ways yextendand which communicates with the bore or bearing of the box by meansofthe slots or spaces 12, 12 and 13.

Within the bore or bearing of the box or casing 5 and sustained by theways 8, 8 is a roller bearing ca e comprising the rings 14, 14 and 15whic are spaced apart on the rods or shafts 16, 16 so as to registerwith the spaces l2, 12 and 13 while on said rods or shafts 16, 16 arejournaled the rolls 17,

17 which bear at their ends against; the' rings 14, 14 and 15. rlhediameter of the shoulder 7 is such that the roller bearing thus formedmay slide through the opening of such shoulder into place on to the ways8, 8 until the inner ring ,12.comes in contactwith the inturned wall, 6of casing 5 and, as it is desirable to provide the outer endof the boxwith an end bearing somewhat similar, in its function to said wall 6,and at the same time to increase the height of the wall 11 so that thelevel of the oil in the reservoir formed by wall 9 and its ends may beabove the upper surface of the ways 8, 8 I provide the stepped shoulder7 with the ring 18 removably seated in said shoulder.

The shaft A journaled in said roller bearing has at its outer end theannular groove a with which is engaged the yoke piece 19 having bearingsat its ends against the face of shoulder 7, and this yoke piece 19 isheld in place by the end closure 20 having the screw plug 21 and securedto the casing 5 in any manner so that the casing 5, the roller bearingand said shaft Av are held together against material independentlengthwise movement of said parts. Preferably the shaftvor axle A issupplied with the'slecve 7J of comparatively soft steel having ahardened peripheral skin but this sleeve does not necessarily form partof the present invention. When ready `for operation oil is supplied tothe .reservoir formed by the wall 9 until the oil rises to the ro'ds orshafts 16 of the lowermost rolls 17, 17 so that oilis supplied to thebores ofsaid rolls which oil, in the rotation of Asaid roller bearing iscarried around shaft or axle A and, to a large extent, drains from therolls 17, 17, when in their uppermost position, on to the shaft or axleA or on to its sleeve 7) as the case may be.

Having thus described my invention I claim as new and desire to secureby Letters Patent.

A lubricating journal box comprising a 'casing having at its lowerportion an oil bore, ating Fitting into said opening, and a I closurefor the open end of sa' and said ring whereby the joint between said 1dcasing, said ring and said box is closed, substantially as closurehaving a, clearance chamber to re.- described. ceive the end of theshaft journaled in the ELIEL L. SHARPNECK. 5 box and an integral flangeupstanding in- Witnesses:
